The Green Party conference has voted overwhelmingly against joining any pre-election pact with other parties.
Delegates accepted a motion ruling out an electoral alliance, saying it would only open talks about forming a government after an election.
Cork South Central TD Dan Boyle, who proposed the motion, said it was vital that the Green Party was seen as distinct.
The full wording of the motion reads: " That the Green Party / Comhaontas Glas will enter into the next general election as an independent party, with the aim of getting as many Green Party TDs as possible elected, and only after the election will it open negotiations with other parties with regard to the possibility of entering Government."
Dublin South TD Eamon Ryan proposed an alternative motion which called for the option of entering an alliance to be kept open. But delegates voted five to one against this option.
Earlier the Party accused the Government of wasting huge sums of taxpayers' money throught its consistent failure to manage the State's affairs.
Finance spokesman Dan Boyle said his party's creative solutions which include carbon tax and refundable childcare tax credits would potentially save the Exchequer billions of euro.
Deputy Boyle told the Green Party annual convention in Cork that the Government had shown itself incapable of managing the affairs of the State. "While the Government parties claim to be pro-business, they are anything but businesslike.
"They continue to waste huge sums of taxpayers' money and abuse the trust of the electorate. Whether these errors are made through incompetence or self-interest, they are unacceptable," he said.
Mr Boyle added: "This Government has created numerous problems. The Green Party is confident that our ideas and our way of doing business will be part of the solution.
"We are here to show that the Green Party has solutions such as carbon tax, refundable childcare tax credits, a special pensions saving scheme for those on low incomes, the substitution of commercial rates with site value taxation and the correct and purposeful targeting of tax reliefs."
